Title: A resiliently deformable element for use as a buffer stop in a motor vehicle suspension
Inventor: TONDATO CARLO F
IPC: F16F9/38
Filed: 1988-08-02
Abstract: A resiliently deformable element (3) made of a microcellular elastomeric material has an upper part (16) adapted to contact a suitable seat of the motor vehicle chassis and a lower part (19) against which a surface of the casing of a shock absorber (1) can contact. The first part (16) is delimited internally and externally by coaxial surfaces (17, 18) and the second part (19) is annular, coaxial with the first part, projects axially from it, and is delimited by inner and outer surfaces of revolution (20, 21) each of which is generated by rotating about the axis (22) of the element a segment of a curved line the centre of curvature of which is located on the same side of the line itself as that on which the said axis (22) lies. The segments are chosen so that sections through the second part (19) of the element (3) taken on planes orthogonal to the axis (22) of the element itself, have decreasing cross-sectional areas with increasing distance from the first part (16) of the element. …<IMAGE>…

Title: Shield for i.v. device
Inventor: WALLACE HENRY GEORGE
IPC: A61M5/00
Filed: 1988-10-18
Abstract: The invention provides an assembly of a needle shield (6) for a needle channel (10) and a self-sealing diaphragm (5), wherein the needle shield (6) is generally cup-shaped and is provided with an aperture (8), said self-sealing diaphragm (5) being retained in the aperture (8), the arrangement being such as to protect the fingers of the operative from needle-stick by the miss-direction of a hypodermic needle. The diameter of the aperture (8) may approximate to, or be smaller than, the internal diameter of the inlet of the needle channel (10) so that not only is needle-stick obviated, but also the tendency of the needle point to tear the seal-sealing diaphragm (5) is significantly reduced.

Title: Transmission of stored digital audio signals
Inventor: KIRBY DAVID GRAHAM
IPC: G11B27/034
Filed: 1988-12-16
Abstract: Digital audio data is transferred from one disc store to another in two or more phases. In the first phase data is transmitted at low quality, e.g. at a reduced sample rate and/or number of bits per sample, to allow the transmitted data to be received relatively quickly. Editing of the received data can then commence, and in one or more subsequent phases the missing data is transmitted to increase the received signal to full quality. Selected portions of the signal, which may be predetermined in the data or requested by the user, can be sent in full detail in the first instance.

Title: Pipe couplings
Inventor: EKMAN THURE
IPC: F16L37/34
Filed: 1991-01-04
Abstract: A pressure-reducing member is arranged in a coupling part (1) and can be actuated when the male part is coupled together with a female part (2). The coupling part comprises an inner, longitudinally displaceably arranged unit (3, 4) which in a starting position keeps the media pressure confined in a first chamber (25) in the coupling part and in an actuation position opens for media so that the latter gains access to the second chamber (26) in the coupling part (1). The pressure-reducing member comprises a lead-off channel for media pressure and a shut-off element (19) arranged in the latter, and it can be actuated at the end face of the coupling part via an actuation member (21a, 21b, 21c) which can cooperate with the shut-off element. The actuation member is designed sealed-off in order to prevent lead-off media from reaching the end face of the coupling part (3) in question. The channel on both sides of the sealing element (19) can be connected to the first and second chambers (25, 26). Upon actuation of the pressure-reducing member, the said chambers form two communicating vessels/chambers via the connections to the channel and the opened shutoff element (19). <IMAGE>

Title: Drying used sand, before cleaning by attrition
Inventor: WILHELM LUDGWIG
IPC: B22C5/00
Filed: 1991-03-08
Abstract: A process is described for the recovery treatment of predominantly clay-bonded used foundry sand to allow its re-use in place of new sand. In such processes the sand grains are repeatedly accelerated and decelerated and are rubbed against one another by a combined impact stress and shearing stress so as to free the adherent shell from the sand cores and the shell material thus freed is removed pneumatically. According to the invention the process further comprises the step of setting the water content of the old sand before the stress treatment at most one per cent by weight. The low water content avoids the formation of lumps during the recovery process.

Title: Telephone
Inventor: JOO SHIN
IPC: H04M1/27495
Filed: 1991-07-15
Abstract: A telephone for identifying an intended recipient enables a user to input a telephone number and/or a shortened one of the recipient, and the telephone acoustically outputs information about the intended recipient such as his name and/or firm name. allowing the user to determine whether the telephone number and/or shortened one has been correctly dialled. Multiple acoustic signals are stored in a memory (3), at addresses corresponding to respective telephone numbers or speed-dial code numbers, by the user when the device is in record mode. Then to place a call, the user dials a telephone number, and the number is used to address the appropriate number from memory, and to address corresponding name and/or firm name which is converted into an analog signal, which is outputted to an electroacoustic transducer such as a speaker (12). The actual dialling of the number is delayed for a short period to give the user the opportunity to hear the acoustic information, and cancel the call if it is a wrong number. <IMAGE>
